A photograph posted on imageboard 4chan appears to show a leaked 21 August 2017 memorandum from the US Army Cyber Protection Brigade. The document alludes to the US Army teaming with the National Security Administration (NSA) in ongoing successful investigations against "Tor, I2P, and VPN," with a request for additional funding for further projects against cryptocurrencies.

There is a growing trend in the employment of Stealth address and ring signatures that will require additional R&D."
